PLANT PARASITIC NEMATODES OF PLANTS AND WEEDS AT ELSADAT DISTRICT

Abstract

Menoufia governorate is one of the agricultural governorates that characterized by planting many variations of different crops, whether fruit, vegetables or field crops, especially the center and city of El-Sadat, which is considered the desert back of the province. Plant parasitic nematodes considered to be the most severe parasites that affect these plants, whether fruit, vegetables or field crops and cause significant economic losses. This study aims to identify the most important species of nematodes that infect some fruit trees and cause dislocated economic losses in the city of El-Sadat, Menoufia on four fruit trees, namely : orange - mango - grapes – peach, also the most important nematode genera which infect five field crops and associated weeds (Clover and Cynodon dactylonweed), (Potatoes and Cyperus rotundus weed), (Wheat and Echino chloacolonumweed) &; (Beans and Sonchus maritimaweed) & (Cabbage and herboid weed). Composite soil samples from the rhizosphere of the tested plants were monthly collected, at summer period (April 2017 – September 2017) and the others represented Winter period (October 2017 – March 2018). Samples were transferred to the laboratory where plant parasitic nematodes were extracted by modified Baermann funnels and nematodes were counted using dissecting microscope and identified using stereoscopic microscope.
